Onset of antiferromagnetism in heavy fermion metals
A. Schroder, G. Aeppli, R. Coldea +6
There are two views of antiferromagnets. The first proceeds from atomic physics, which predicts that atoms with unpaired electrons develop magnetic moments. In a solid, the couplin…
Classical Heisenberg antiferromagnet on a garnet lattice: a Monte Carlo simulation
O. A. Petrenko, D. McK Paul
We have studied a classical antiferromagnet on a garnet lattice by means of Monte Carlo simulations in an attempt to examine the role of geometrical frustration in Gadolinium Galli…
High Magnetic Field Behaviour of the Triangular Lattice Antiferromagnet, CuFeO_2
O. A. Petrenko, G. Balakrishnan, M. R. Lees +2
The high magnetic field behaviour of the triangular lattice antiferromagnet CuFeO_2 is studied using single crystal neutron diffraction measurements in a field of up to 14.5 T and…
Critical Behaviour in the Spin Fluctuations and Superfluid Density of LaSrCuO
C. Panagopoulos, B. D. Rainford, J. R. Cooper +2
We study the doping dependence of low frequency spin fluctuations and the zero-temperature superfluid density of LaSrCuO using the muon spin relaxation (SR) and…
Spin waves and electronic interactions in La2CuO4
R. Coldea, S. M. Hayden, G. Aeppli +5
The magnetic excitations of the square-lattice spin-1/2 antiferromagnet and high-Tc parent La2CuO4 are determined using high-resolution inelastic neutron scattering. Sharp spin wav…
